I wanted to go down the route of 28 Days Later instead of Doomsday. Apparently, the script writers for Peninsula opted for the latter.My point of view: your fan-fic (@Gillan1220) is largely better and more interesting that Peninsula.
As TV Tropes points out regarding some good points to ponder for Peninsula which I actually tackled here.
- They Wasted a Perfectly Good Plot
- North Korea and South Korea are said to have undergone reunification during the initial zombie crisis. This is only mentioned in a throwaway line in the beginning of the movie and is not elaborated further.
- During the four years that have passed since Train To Busan, the entire Korean peninsula – which includes both North Korea and South Korea – has been abandoned and deserted. Aside from the brief talk show interview in the beginning with mentions of Korean reunification and other countries rejecting Korean refugees, nothing is brought up about the worldwide ramifications of the collapse of one of the most developed countries in the world and one of the most infamous authoritarian dictatorships in recent history.
